The air duct 35 includes an air inlet duct 351 disposed between the axial air inlet side 321 and the air inlet 33, and an air outlet duct 352 disposed between the radial air outlet side 322 and the air outlet 34.

The air inlet duct 351 is located in the air inlet cavity or the air inlet duct 351 directly forms the air inlet duct 351, and the air outlet duct 352 is located in the air outlet cavity or the air outlet cavity directly forms the air outlet duct 352.

In this embodiment, the fan assembly further has a volute 36 disposed on the base 316, the turbo fan 32 is disposed in the volute 36, the volute 36 has a volute inlet 361 opposite to the axial inlet side 321, a volute outlet 362 opposite to the radial outlet side 322, and a volute cavity communicating the volute inlet 361 and the volute outlet 362, the turbo fan 32 is disposed in the volute cavity, the inlet 351 is formed between the volute inlet 361 and the inlet 33, and the outlet 352 is formed between the volute outlet 362 and the outlet 34.

As shown in fig. 13, in this embodiment, for convenience of implementing the installation and fixation of the fan assembly, the turbo fan 32 is fixed on the base 316, and the volute 36 is covered outside the turbo fan 32 and is installed and fixed on the base 316. A volute positioning plate matched with the volute 36 is arranged on the base 316, and the volute 36 is buckled on the volute positioning plate.
